PLOW.

Specification of Letters Patent.

atented May 7, 1907.

Application filed January 14, 1907. @arial No. 352,250,

To all whom it may concern:

Be it known that I, WILHELM G. DANIEL- sEN, a citizen of the United States, residing at Logan, in the county of Cache and State of Utah, have invented a new and useful Plow, of which the following is a specification.

This invention has reference to improvements in plows, more especially of the disk type wherein the disks are mounted upon a suitable frame and supported upon wheels, and is provided with a seat for the driver.

The present invention is directed more particularly to the mechanism located at the rear of the plow whereby the rear supporting or controlling wheels may be variously adjusted to meet the various demands made upon a plow of this character.

The invention consists essentially in providing for the wheels an axle having its ends bent at angles in opposite directions and so mounted upon a supporting member that it may be moved to travel in planes at various angles to the length of the plow for the purpose of facilitating turning, and also provided with means whereby the axle may be rotated upon a horizontal axis to carry the supporting wheels to relatively different vertical positions.

The invention will be more fully understood by reference to the following description taken in connection with the accompanying drawings, in which,-

Figure 1 is a perspective of a rear portion of a disk plow constructed in accordance with my invention, Fig. 2 is a vertical section taken through the plane of the rear axle 5 and Fig. 3 is a longitudinal section, partly in elevation, of the portion of the plow wherein provision is made for the adjustment of the rear wheels with relation to the main frame.

Referring to the drawings, there is shown a framework 1, which may be substantially triangular in shape, and on one side member of this frame are a number of bearings 2 in which is journaled a rock shaft 3 carrying arms 4 at suitable intervals, which arms engage brackets 5 to which latter are attached the disks 6 constituting the plowshares.

The plow adjusting mechanism need not be particularly described since this structure forms no part of the present invention and may be of any approved type. The plow disks are under the control of a lever 7 having a ratchet tooth 8 engaging with a curved rack 9 fast on the frame of the plow, so that the plow disks 6 may be adjusted by means of this lever into and out of engagement with the ground. The lever 7 is within reach of an operator seated upon the seat 10 fast on the rear end 11 ofthe framework of the plow. This rear end 11 has a casting formed with an extension 12 in which is formed an arcshaped slot 13 and at the axis of the slot 13 the part 11 is provided with an upright hollow stud 14.

Located below the part 11 and parallel therewith is a rod 15 having its front end 16 up-turned at right angles to the main portion and extended into and through the hollow stud 14. This rod 15 is held against the under side of the part 11 by means of a U- shaped clip bolt 17, the legs of which extend upward through the arc-shaped slot 13 and there receive bolts 18 which serve to clamp the rod 15 against the under side of the-part 11; but, as will be readily understood, the rod 15 may be swung around the extension 16 thereof as an axis through an arc determined by the length of the slot 13. Upon the outer rear end of the rod 15 is a block 19 which is free to turn upon the rod 15 but is to have practically no longitudinal play thereon. Below the rod 15 the block 19 is formed with a boss 20 through which is a perforation for the passage of the axle 21 located at the rear end of the plow. This axle 21 consists of a straight portion, continuing from each end of which isa bent portion 22 and. the extreme end of the bent portion 22 is again bent, as shown at 23, so that the two parts 23 lie in different planes but parallel one to the other; and also so that, when the axle 21 is rotated, the bent parts 22 will carry the parts 23 in circular paths but in opposite directions around the axis of the part 21. The two parts 23 constitute supports for the hubs of wheels 24 held thereon by collars 25, each of which have frusto-conically shaped peripheries and are mounted upon the axle with the cone faces located in the same gen eral direction.

The axle is prevented from moving longitudinally through the boss 2O by means of a collar 26 on one end of said bess and another collar 27 on the opposite side of said boss, both collars being held fast upon the axle by set-screws, as shown, so that, when desired, longitudinal adjustment of the axle may be effected. The collar 27 is prolonged into or has formed thereon a lever 2S having a IOO thuinb-latch tooth engaging the teeth. of a segmental rack 30 fast on. or formed on the corresponding side of the block 19.

Now, supposing that the plow is in operation, it will cut in the ground a 'furrow`31 diagrammatically represented in Fig. 2. The axle 21 being appropriately turned in the bearing formed in the block 19 will carry the wheel 24 at the left to the top of the ground while the wheel 24 at the right will rest in the furrow. In this position, the peripheries of these wheels vbeing conically shaped and the wheels riding at an angle as shown, they will travel upon the top of the ground and bottom of the furrow respectively, while the plow frame remains substantially horizontal, and by turning this axle the wheels may be `made to accommodate themselves to any depth of furrow, while the base of the coneshaped periphery will prevent any lateral displacement of the rear end of the plow due to the lateral thrust of the plow disks. Now, by adjusting the rod 15 around its axis 16 the relative position of the wheels 24 with relation to the main body oi the plow is changed and the plow disks 6 can in this man.- ner be set to travel at any desired angle within the range ol: adjustment to the line of travel of the structure as a whole. The result is that the width of cut of the plow can be readily adjusted, so that a wide or narrow furrow can be made by the simple expedient of turning the rear wheels upon the axis 16 and then locking them in the adjusted position by the clip 17.

In the position oi the axle shown in Fig. 2 the wheels are adapted to follow the plow when the latter is making a furrow. If, now, it be desired to turn the low, say, to the right, the lever 28 is pulle back to the position shown in Fig. .1 and this means that the axle 21 will be rotated until the wheel 24 to the right of Fig. 2 is higher than the wheel 24 at the left, and the axle will tilt around the axis formed by the rod 15, so that the wheels will still lean toward the right and will accommodate themselves to the turning of the plow toward the right. Ii, now, the wheels are in 'the position shown in Fig. 2 so far as the relation of the axle to the block 19 is concerned, and the plow is running on level ground, the wheels will be in a position to permit the ready turning of the plow as a whole to the lel't, for, under these circumstances, the wheels will then be leaning toward the le'lt. This accommodation of the plow structure to the several conditions mentioned is due in part to' the manner in which the axle is bent; that is, in such manner as to terminate in two hub-supporting ends parallel with each other but in di'llierent planes and on opposite sides ot the main axis of the axle. Also, the free swinging of the axle in a vertical plane around the rod support 15 as an axis contributes to this result, and the adjustment of the axle support 15 to the vertical axis enables me to easily adjust the width oi' cut of the plow disks.

I claim:-d

1. In a plow of the character described, an axle for supporting a pair of rear wheels coinprising a central portion, connections between tlie same and the plow `frame, and two end portions lirst bent in opposite directions from the central portion and then into two wheel-carrying ortions parallel to each other but locatedp in different planes, in combination with wheels having frusto-conical peripheries the bases of which face in the same direction.

2. In a plow of the character described, a wheel axle support com rising a rod movable in a horizontal plane a out a vertical axis,

means for adjusting and holding the rod, an

axle-holder mounted upon said rod and movable in a plane at right angles to the plane of movement ol said rod, an axle extending through the axle-holder and rotatably adjustable therein, and connections between said axle and said holder for adjusting and locking the axle in osition thereon.

3, In a plow of tiie character described, a rear axle support moving in a horizontal plane around a vertical axis, means for holding the support in adjusted positions, a rotatable support for the axle mounted upon said horizontally-adjustable support, an axle journaled in said rotatable suport and bent at its two ends in opposite irections and terminating at the ends in two parallel parts located in diii'erent planes, and means be- IOO tween the axle and the rotatable support for adjusting the axle about a longitudinal axis. 4. In a plow of the character described, a rod having one end bent at right angles and Aseated in a bearing formed on a fixed portion of the plow frame, a clip passing through an arc-shaped slot in the said iixed portion of the plow frame and sup orting the said rod, a rotatable block carried) by the outer end of said rod, an axle bearing extending through said rotatable block at right angles to itsv plane of rotation, an axlel carried by said block and having its ends oppositely bent to lie in parallelism but in different planes, means `for holding the axle to the block but permitting longitudinal adjustment of the axle, connections between the axle and block for adjusting the axle rotatively therein, and wheels carried by the axle and having irustoconical peripheries.

In testimony that I claim the foregoing as my own, I have hereto ai'Iixed my signature in the presence of two witnesses.
